As mentioned..   3x not a charm here.

I have this isseu every time.
Clearcoating without gelcoat would be an option. But allso that isnt easy with small holes like this.

Now i used gelcoat. Hoping it would help.

Gel had cured at 25 degrees for 5 hours was dry to touch.

I used 3m high tack clear spray adheasive to hold the fibers in place. (AS LITTLE AS POSSIBLE)


on the vacuum catch pot the dail says my vacuum is 100%
I leace the pump running over night.  In the morning when the resin is hardned the vacuum line form the ez composite starter kit to the pot is flat from the vac. 

(I dont have an official cacuum pump.  I use a 35l/m fridge pump. Whitch seems to work fine.   I can add an extra pump if i need more cfm...)
If my vac is to strong.. i can make a bleedvalve to reduce vacuum.   

But idialy i would love to have a perfect finish.

I use easy lease release agent..  denoulding is a breeze..

Sometimes you can even throttle the feed line on a 6mm hose to slow things down.  Certainly in your case it can't hurt. 

Bridging can be a right pain.  You can use spray tacks but very sparingly otherwise they make a mess of the surface finish. 

You have to take care with every layer to avoid bridging as well as with the bagging stack.  You can chop up the peel ply and mesh with an overlap where necessary to make it easier to avoid bridging.

I allready chop the peel and mesh to avoid bridging. But yes. The white mesh that came with the kit is quite nasty in sharp corners.      I did a slooow infusion with 6mm and il see what comes out.

Prepreg is awsome. But then i do need an autoclave.  And thats something i cant afford.
So. Hand layup and infusion will be my choices.
Hand layup is most used in these boats and does work fine.   But infusion would be awsome when i master the tecnique.
